Abstract

本实用新型涉及一种可以使螺杆不暴露在外面的新型膨胀螺栓,包括螺杆、平垫、膨胀套管、锥体螺母;锥体螺母为锥体状,其一端的外径大于另一端的外径;螺杆穿过平垫中孔,锥体螺母螺纹连接在螺杆上,膨胀套管卡在平垫和锥体螺母之间。使用时只要拧紧螺杆,螺杆拉动锥体螺母,使膨胀套管膨胀运行。螺杆是往里走,这样使用中非常方便。当拧紧后,只有螺帽在外面,螺杆是放在里面的,十分美观。

Description

新型膨涨螺栓
本实用新型涉及一种膨涨螺栓,特别是一种螺杆不暴露在外面的新型膨胀螺栓。
现行社会上销售的膨涨螺栓都是螺母带动螺杆,螺杆往外走,在安装使用中,由于螺杆与膨涨套管同时放在打好的孔内,又要露出一段螺杆,这样使用起来非常不方便。当拧紧后还有好长一段螺杆露在外面,十分不美观。
本实用新型的目的在于提供一种使用时螺杆不露在外面的新型膨胀螺栓。
本实用新型的目的是这样实现的:包括螺杆、平垫、膨胀套管、锥体螺母;锥体螺母为锥体状,其一端的外径大于另一端的外径;螺杆穿过平垫中孔,锥体螺母螺纹连接在螺杆上,膨胀套管卡在平垫和锥体螺母之间。
使用时只要拧紧螺杆,螺杆拉动锥体螺母,使膨涨套管膨涨运行。
本实用新型的特点在于:螺杆是往里走,它是先放膨涨套管,放好安装的产品,再用螺杆拧紧,这样使用中非常方便。当拧紧后,只有螺帽在外面,螺杆是放在里面的,十分美观。
图纸说明:
图1是本实用新型的膨胀螺栓的剖视图;
图2是免焊式膨胀螺栓的剖视图;
图中1.螺杆2.平垫3.膨涨套管4.锥体螺母1-1.易断处1-2.拧紧后留下的圆平帽
在图1中,使用时螺杆1穿过平垫2、膨涨套管3和锥体螺母4连接,当使用时,拧紧螺杆1。图2只是在图1的基础上,根据金属疲劳的道理,增加了一点不易被卸的功能。
现在有些人用膨涨螺栓拧紧物体后,还要用电焊再焊一焊,十分麻烦,还存在一定的危险性,现在图1的基础上,把螺杆1加长一点在图2中的1-1处加工细,留1-2圆平帽,这样在拧紧1螺杆后,由于1-1处细,此处的强度不如其它地方,当最后加力拧紧螺杆时,1-1处被紧断,留下1-2圆平帽仍起到加固产品,不易被卸的作用。
